alt Hacker NewsThis is a grossly disingenuous strawman. The top comment as of posting clearly states "The sheriff that arrested him should face criminal charges for misuse of authority." False imprisonment is against the law, this situation is far from merely doing something we dislike.
False imprisonment generally doesn't apply when due process is followed, like getting a warrant.
You'd have to change the law to allow for prosecutions in cases like this, and that change would likely be weaponized in other cases.
